Top Tips to Prevent Mould Build-Up Around Bathroom Windows
Advice from Aspen Home Improvements

Mould build-up around bathroom windows is a common issue that many homeowners face, but with the right preventative measures, you can keep your
windows clean and mould-free. At Aspen Home Improvements, we understand the importance of maintaining a healthy and hygienic bathroom environment. In this blog article, we'll share our top tips and advice for
preventing mould build-up around bathroom windows, ensuring a clean and comfortable space for you and your family to enjoy.
1. Proper Ventilation:
- Adequate ventilation is crucial for preventing moisture build-up in the bathroom, which can lead to mould growth. Ensure your bathroom is properly ventilated by installing an extractor fan or opening windows during and after showering to allow steam to escape.
- Consider installing a window vent or trickle vent to improve airflow around your bathroom windows, reducing the risk of condensation and mould formation.
2. Use Mould-Resistant Paint:
- When painting bathroom walls and window frames, opt for mould-resistant paint formulations that are specifically designed for high-moisture environments. These paints contain additives that inhibit mould growth, providing an extra layer of protection against mould build-up.
- Regularly inspect painted surfaces for signs of wear or damage, and touch up any areas where the paint may be peeling or flaking to prevent moisture infiltration and mould growth.
3. Keep Windows Clean and Dry:
- Regularly clean and dry bathroom windows to remove any moisture or condensation that may accumulate on the surface. Use a mild detergent and water solution to clean window frames and glass panes, and wipe them dry with a clean, lint-free cloth to prevent water spots or streaks.
- Pay particular attention to window seals and gaskets, as these areas can trap moisture and provide an ideal breeding ground for mould. Clean and inspect seals regularly, and replace any damaged or deteriorated seals to maintain a watertight seal around your windows.
4. Seal Gaps and Cracks:
- Inspect window frames and caulking for gaps, cracks, or gaps where moisture can penetrate and accumulate. Seal any gaps or cracks with a waterproof silicone sealant to prevent water infiltration and reduce the risk of mould growth.
- Ensure that window seals are in good condition and provide a tight seal around the window frame to prevent moisture from entering the space between the window and the wall.
5. Monitor Humidity Levels:
- Use a hygrometer to monitor humidity levels in your bathroom and ensure they remain within the recommended range of 30-50%. Excess humidity can contribute to mould growth, so take steps to reduce humidity levels if necessary, such as using a dehumidifier or increasing ventilation.
- Consider installing a humidity-sensitive exhaust fan that automatically activates when humidity levels rise above a certain threshold, helping to maintain optimal humidity levels and prevent moisture build-up.

By following these top tips and advice from Aspen Home Improvements, you can effectively prevent mould build-up around your bathroom windows and maintain a clean, healthy, and mould-free bathroom environment.
Taking proactive measures to address moisture issues and improve ventilation will not only protect your windows from mould damage but also ensure the longevity and integrity of your bathroom fixtures and finishes.
